Spinning the Barrel

Barrels of oilBP and the media express quantities of oil gushing from BP's leak in the Gulf in different ways. The amount of oil coming out of the leak is most frequently expressed in barrels, but how much is that? Can people really relate to a barrel as a quantity? After all, we buy staples like gasoline, milk, and water by the gallon. To make it even more complicated for the public to understand the quantities being discussed, the amount of liquid in a barrel varies with what is being measured. Barrels of chemicals or food, for example, contain 55 gallons. A whiskey barrel is 40 gallons; a barrel of beer contains 36 gallons; a barrel of ale contains 34 gallons. (And the latter two are imperial gallons, which are just under two-tenths more than an American gallon.) All these variations in the barrel as a quantity of measure only further confuse the concept of what a barrel of oil looks like. Moreover, since oil companies started shipping oil in tankers they rarely actually ship oil in barrels anymore, so the barrel as a measurement has less practical use.

Do the Math, Check Twice for Spin

When oil is coming out of the leak, BP tends to express the quantity in barrels, but when the company talks about how much oil it is collecting or incinerating, it will report the quantity in gallons. The day BP began burning siphoned oil from the ruptured well, for example, they reported that by noon that day they had burned 52,500 gallons of oil. It sounds like a significant amount, but that's just 1,250 barrels -- a microscopic amount compared to what is gushing from the blowout each day.

In any case, when reading or hearing news about the Gulf oil disaster, pay attention to how quantities are expressed. One barrel of crude oil equals 42 U.S. gallons, so multiply barrels by 42 to get the quantity being quoted in more familiar gallons. You may have to do some math to better interpret the quantities being discussed.


Come on guys and gals, you know where the conversion tables are, this is not the thing to bleat about.

Radiation leak was in so many "Becquerels" Who knew what a becquerel was? and how could anyone relate to it. this disaster is being reported in exactly the same way, in terms that make it dificult to comprehend but with a little human interest thrown in here and there. One last point. I don't believe for minute that BP will pay for the clean up or anything else. Sure they'll front the money but in the end prices will go up and we will pay for it all at the pump.
